Thanks to the lovely Ross (good luck in your future ventures fella!) for bringing Luciferous Logolepsy to my attention:
Luciferous Logolepsy [is] a collection of over 9,000 obscure english words. Though the definition of an "english" word might seem to be straightforward, it is not. There exist so many adopted, derivative, archaic or abandoned words in what we loosely define as the "English Language", that a clear-cut definition seems impossible. For the purposes of this project though, words are included that may stretch any basic definitions. Particular attention has been paid to archaic words, as they tend to be more evocative - as if their very age lends additional meaning or overtones. Current personal favorites include skirr, epicaricacy and schizothemia.
